GeForce 930M vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which comes with GPU core speed of 700 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 430 should in theory be much better than the GeForce 930M overall. (explain)

GeForce GT 430		28800 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 930M should be much (more or less 99%) better at anisotropic filtering than the GeForce GT 430. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 11072 (99%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 930M is superior to the GeForce GT 430, and very much so. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 4624 (165%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
